Abstract

Heavy chain subclasses of 121 IgG monoclonal proteins were found to be 74% IgG, 10% IgG, 12% IgG and 4% IgG. Light chain subclasses showed a slight kappa excess among IgG proteins. Electrophoretic studies of these monoclonal proteins and of normal γ-globulin showed IgG had a wide range of mobility including the most slow (electronegative) proteins; IgG and IgG were among the faster moving, while IgG showed medium to slow mobility. The above random distribution of IgG subclasses was found in eighteen monoclonal proteins causing hyperviscosity syndrome, whereas among fourteen monoclonal cryoglobulins there was an excess of IgG and IgG subclasses.

摘要

在121种IgG单克隆蛋白中,重链亚类发现为74%的IgG₁、10%的IgG₂、12%的IgG₃和4%的IgG₄。轻链亚类在IgG蛋白中显示κ链略占优势。对这些单克隆蛋白和正常γ球蛋白进行的电泳研究表明,IgG具有广泛的迁移率,包括迁移最慢(带负电)的蛋白;IgG₁和IgG₃迁移较快,而IgG₂显示中等至较慢的迁移率。上述IgG亚类的随机分布在18种导致高黏滞综合征的单克隆蛋白中被发现,而在14种单克隆冷球蛋白中,IgG₁和IgG₃亚类过多。
